This book is about numbers and so many questions relating to them. What is the nature of numbers are they discovered or invented? What is mystical about them? Mathematicians develop a hierarchy of numbers in which mysterious dichotomies appear. For example, the integer 5 is not the same as the rational 5 which in turn is different from the real 5. The author explains how this conceptual maze does not affect the laypersons' arithmetic. He also discusses such fascinating topics as primes, perfect numbers, inaccessible numbers and many other unsolved problems relating to the treacherous terrain of infinity, which have baffled mathematicians and philosophers alike.

Preface

This book is about numbers. It tries to answer many questions relating to them. What is the nature of number? Are they discovered or invented? Are they eternal or immortal? What are finite and infinite numbers? What is mystical about them?

It shows, how starting with a collection of objects a hierarchy of numbers-the natural numbers, integers, rationals, irrationals, real numbers and complex numbers can be constructed. It also discusses such topics as primes, perfect numbers, infinite numbers, cryptopgraphy, Fibonacci numbers, the Fermat's last theorem and also many unsolved problems relating to numbers.

The only prerequisite for understanding this book is the knowledge of high school mathematics and a desire to know more about numbers. All mathematical concepts which the common reader is not likely to be familiar are explained at the appropriate stages. Since this is not a treatise on mathematics most theorems are stated without proof.

Most of these results can be appreciated intuitively except those which baffle even mathematicians. I hope, the many illustrations which I have included will enable the reader to have an insight which a rigorous formal treatment cannot provide.

Though meant for a general audience, the students of mathematics and philosophy should also find the book interesting. Bertrand Russell often reprimanded philosophers for not learning sufficient mathematics. A similar criticism can be leveled against mathematicians who feel that philosophy is either irrelevant or far beneath their intellectual level.

With their superior logical mind mathematicians can create countless systems which are self-consistent. Most of these systems are, however, drab unless they have a philosophical dimensions. If mathematicians care to develop a philosophical approach to their problems, they will find a new depth which will enable them to unify and solve many problems which appear disparate as well as intractable. What's more, they will find, to their surprise, tha philosophy can provide a link between their abstruse world of symbols and the world in which common people live.

There are a few books on the philosophy of mathematics, but I have not come across a treatise which exclusively deals with numbers. I hope this book will fill this void.

I finally got my nearly $300 Meenakari earrings today. They were promised in 4-6 days but it took a week for them to be shipped. Then it was 4-6 days. When I saw them I had mixed feelings. They are cute but it took me a half hour to get them in my ears as the posts are really large in diameter. I had to use vaseline and force them through and then the screw on backs (a good thing) wouldn't line up. There seems to be something inside the screw on locks that act as a securing agent. Any way most of the things I've got from ExoticIndia were gifts and acceptable.
